Demir Korcan , Kattan Walaa E , Zou Minjing , Durmaz Erdem , BinEssa Huda , Nalbantoglu Ozlem , Al-Rijjal Roua A , Meyer Brian , Ozkan Behzat , Shi Yufei

Background: The CYP27B1 gene encodes 25-hydroxyvitamin D-1α-hydroxylase. Mutations of this gene cause a rare autosomal recessive disorder, vitamin D-dependent rickets type 1A.Objective and hypotheses: To investigate CYP27B1 mutations in children when rickets was associated with normal or high vitamin D levels and low or inappropriately normal calcitriol levels.Method: All coding exons and intron-exon boundari...

Novel Heterozygous ACAN Mutations in Short Stature: Expanding the Clinical Spectrum

Sentchordi Lucia , Barraza Jimena , Rivera Carlos Ivan , Marcos M. Victoria , Sanchez M. Consuelo , Vallespin Elena , Pozo Angela del , Heath Karen E.

Background: Homozygous aggrecan (ACAN) mutations have been described in a few skeletal dysplasias whilst more recently, heterozygous ACAN mutations have been reported in few families presenting with idiopathic short stature with advanced bone maturation and premature growth cessation.Case presentation: We describe two novel heterozygous ACAN stop mutations, detected using a skeletal dysplasia NGS panel and confirmed by Sanger sequencing...

Objective: Congenital hyperinsulinism (CHI) is the most common cause of hypoglycaemia in children. Early identification and management is crucial to prevent irreversible brain damage. CHI has a heterogeneous clinical presentation, histology and molecular biology. We aim to discuss the clinical characteristics and genotype–phenotype correlations of Turkish CHI patients from a single centre.Design and methods: A total of 15 patients with CHI were recr...

Background: Congenital hyperinsulinism (CHI), is the most common cause of severe hypoglycaemia in neonates and infants. The cornerstone of medical therapy is diazoxide. Octreotide, a somatostatin analogue, is the second therapeutic option in diazoxide unresponsive cases. However, due to its short half-life and requirement of multiple daily doses, lack of compliance may cause recurring hypoglycaemia and related neurological deficits, particularly for the family with low socioec...

Unexpected impact of sex hormones on B-cells in trans- and cis-gendered healthy young people

Peckham Hannah , Rosser Elizabeth C , Radziszewska Anna , Robinson George , Martin-Gutierrez Lucia , De Gruijter Nina M , Jury Elizabeth C , Butler Gary E , Ciurtin Coziana ,

Background: Cis-gender females are known to mount stronger immune responses to invading pathogens or vaccines than cis-gender males. However, this is also associated with increased risk of autoimmunity. Little is known about the immunophenotypes of transgender individuals on gender-affirming hormonal treatment, despite growing evidence that hormones influence the immune system. Via the process of class-switch recombination (CSR), B-cell immunoglobulin isotype ...

Impact of the COVID-19 pandemic and related lockdown measures on lifestyle behaviours and quality of life in children and adolescents with severe obesity

Welling MS , Abawi O , van den Eynde E , van Rossum EFC , Halberstadt J , Brandsma AE , Kleinendorst L , van den Akker ELT , van der Voorn B ,

Introduction: Lockdown measures following the COVID-19 pandemic are shown to have greatly affected lifestyle behaviours and health-related quality of life (HRQoL) of children. The impact on children with severe obesity has not yet been described. Aim of this study was to investigate the impact of COVID-19 lockdown on eating behaviours, physical activity (PA), screen time, and HRQoL of children (including adolescents) with severe obesity....

Background and Objectives: Achondroplasia (ACH) is characterized by severe short stature with a height deficit of approximately 6 SDS below that of average stature. Our objective was to evaluate the impact of height deficit on health-related quality of life (HRQoL) and functional independence in children with ACH.Methods: Height Z-score, HRQoL, and functional independence data were obtained from children with ACH who enr...

Aim: to examine the effects of supervised cycling sprint interval training (SIT) on serum osteocalcin, lipocalin-2 and sclerostin levels, and bone mineral characteristics among obese adolescent boys.Methods and subjects: untrained adolescent obese boys (n=14) aged 13.4 ± 0.3 were assigned to either a 12-week SIT group (3 sessions/week) or a non-exercising control group (n=14) who continued with their...

Introduction: It is thought that long-term growth hormone (GH) treatment may impair hepatic glucose production and insulin-dependent glucose utilization, and therefore it is attributed that GH may adversely affect glucose metabolism.Objective: In our study, we aimed to examine the effects of GH treatment on insulin sensitivity and glucose metabolism in patients with GH deficiency after 1-year of treatment.<p class="a...

During the COVID-19 pandemic, a significant increase in Central Precocious Puberty(CPP) has been observed worldwide. The reasons for this phenomenon are yet unclear. In order to evaluate if fear, stress and coping strategies used by children and parents when dealing with negative emotional situations and health issues might have acted as triggers for this phenomenon, we administered specific questionnaires to girls who had a diagnosis of CPP before and after the COVID-19 relat...
